 * Hi all
 * I recently switched this website [tommyandthefallenhorses.com](http://www.tommyandthefallenhorses.com)
   to a new web host. I backed up all the website files and the database as per 
   the codex, and uploaded them to the new server. Now the website is displaying,
   but it is showing these errors at the top of the page, and also won’t let me 
   log in.
 *     ```
       Warning: session_start() [function.session-start]: open(C:\WINDOWS\Temp/sess_b341bec8b54276d363198deaf4670bff, O_RDWR) failed: No such file or directory (2) in /home5/tommyand/public_html/wp-content/plugins/wp-e-commerce/merchants/paypal_certified.php on line 741

       ```
   
 * Any ideas of how to fix this much appreciated.
    Cheers Charlette

 * Hi,
 * t is usually due to spaces, new lines, or other garbage at opening/closing PHP
   file <?php tag or after a closing ?> tag in wp-config.php. It can be other file
   too so need to check error message as it may list file name where the error occurred.
 * One can either upload error file from the backup or edit erroneous file. To edit
   the file one need to check below mentioned points:
 * 1. Download the file mentioned in the error message.
    2. Open that file in a 
   plain text editor 3. Check that the very first characters are <?php 4. Check 
   that the very last characters are ?> 5. Place the cursor between the ? and > 
   6. Now press the DELETE key on your computer and keep that key pressed for at
   least 15 seconds. 7. Now type > and 8. Save without pressing any other key at
   all.
 * That’s it!
 * Thanks,
 * Shane G.
